When Hurricane Sandy ripped through New York, she drove some couples apart — and pushed others together.

“It was like the world might end: We needed to be together now,” said Amy Campbell, 26, a bartender at Iggy’s on Ludlow Street in Greenwich Village, who reunited with an old fling after she texted him to see how he fared during the storm.

Campbell wound up staying at her former flame’s apartment in Bushwick, Brooklyn, for days afterward, listening to ’60s soul compilations.

“You couldn’t get anywhere, we couldn’t work or go out, so we got to camp out,” said Campbell, who added that she hopes they’ll continue dating.

But Lower East Side local Zac Lucien, 21, said Sandy was the last straw for his relationship.

“I’d say it made me realize this relationship was no good,” said Lucien, whose girlfriend left her pad and stayed at a hotel in Queens while he stayed in his apartment during the storm.

“I stayed at home, and it was a peaceful blackout. Sandy had nothing on the fights we had,’’ Lucien said. “My life hadn’t been so easy in months. I didn’t have her chirping in my ear. Once my phone worked again, she called me, and I was like, ‘I’ve had enough.’ . . . When the power came back on, I was, like, ‘I don’t even want to see this girl.’ ”

East Village resident Cristina Gibson, 28, said she wanted her man to step it up during her time of need but he didn’t, and they haven’t seen each other since.

“I just saw the hurricane as a good opportunity for a guy to take initiative and look like a knight in shining armor,” she said.

“I was disappointed that the guy I was seeing didn’t make an effort or do anything. He just went to [be with friends in] Brooklyn, like a loser,” she said.

Still, Derrick Holmes, 27, an IT professional from Linden, NJ, said he got lucky in the fruit section at Pathmark just by asking a comely woman what she was stocking up on.

“I went over with a smile and asked her dumb questions about the apples. I started asking her about Sandy and said, ‘Are you without power, too?’ and she was.”

“We were both off the whole week. It went well,” he said. “I’m smiling, aren’t I?”

Craigslist ads looking for love also popped up during the storm.

On Oct. 31, one married man said in a posting titled “Jewish for Jewish now” that he was looking for “passionate adventurous times” while his family was away during the storm.

The day before, another lonely lady posted that she wanted some “sensual storm fun” and a reason to get out of her apartment.

Manhattan divorce lawyer Raoul Felder said he usually sees an uptick in calls from potential clients seeking a split after storms and other natural disasters.

“I see it after snowstorms, too, because they’ve been together so much they’re just sick of each other,” Felder said.
